So for those who have not kept track of the Quest Project Threads, there has been a 1.1 update. This adds much more content such as more overworlds, more dungeons, more items, and more extra options. When choosing custom options, you are given the choice if you want to limit which worlds and dungeons show up. Dungeon sets are split into groups of 7, with all the dungeons of that group sharing the same 9 palettes.
There are a few changes to gameplay balance.
The Blue Candle is now multi use again, and the Red and Gold Candles are stronger. This does mean you can now only find a Gold Candle randomly in the curiosity shop.
As Ex3 shows a helpful map to keep track of where you have been, Ex4 shows how many items you've collected. Note that the Bomb and Quiver upgrades are not counted for items for an area, since you can encounter them multiple times but only purchase them once.
A 1.11 patch is on the way that fixes a few bugs. It also makes the Ex3 map freeze all action so you don't have to worry about being hit out of it anymore, and adds a difficulty option. This option does not do much with the randomizers, but it makes secrets easier or harder to find. The Easy option also adds a few shortcuts to the more complex overworlds.
The 1.11 patch will also change some of the overworld hints to be more clear or useful.
Anyway, good luck and have fun. At this point, you really won't know what to expect when you play. And play again.
